Abstract
The usefulness of emergent embolotherapy was evaluated in 17 patients with life-threatening hemorrhage from 18 ruptured splanchnic artery pseudoaneurysms. Complete hemostasis was obtained in 16 out of 17 patients by embolotherapy. Of the 12 initial embolization procedures with permanent embolic materials including stainless steel coils, microcoils, and Ivalon, complete cessation of bleeding was obtained in 11. On the other hand, 6 out of 9 initial embolization procedures with Gelfoam particles failed to halt bleeding, and additional embolization with permanent embolic materials was required. Emergent embolization with permanent embolic materials using superselective catheterization should be considered the initial treatment of choice for ruptured splanchnic artery pseudoaneurysms.
